Business Description

History and Organization Huntington Ingalls Industries, Inc. ("HII", the "Company", "we", "us", or "our") is a global, all-domain defense partner, building and delivering the world's most powerful, survivable naval ships and technologies that safeguard America’s seas, sky, land, space, and cyber. For more than a century, our Ingalls Shipbuilding segment ("Ingalls") in Mississippi and Newport News Shipbuilding segment ("Newport News") in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder, making us America's largest shipbuilder. Our Mission Technologies segment develops integrated technology solutions and products that enable today's connected, all-domain force. Headquartered in Newport News, Virginia, we employ over 44,000 people domestically and internationally. We conduct most of our business with the U.S. Government, primarily the Department of War (the "Department"). As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense programs. Ingalls includes our non-nuclear ship design, construction, repair, and maintenance businesses. Newport News includes all of our nuclear ship design, construction, overhaul, refueling, and repair and maintenance businesses. Our Mission Technologies segment provides a wide range of services and products, including command, control, computers, communications, cyber, intelligence, surveillance, and reconnaissance ("C5ISR") systems and operations; the application of artificial intelligence and machine learning to battlefield decisions; defense and offensive cyberspace strategies and electronic warfare; unmanned autonomous systems; live, virtual, and constructive training solutions; platform modernization; and critical nuclear operations. Ingalls Through our Ingalls segment, we design and construct non-nuclear ships for the U.S. Navy and U.S. Coast Guard, including amphibious assault ships, surface combatants, and national security cutters ("NSC"). We are the sole builder of amphibious assault ships and one of two builders of surface combatants for the U.S. Navy. Our Ingalls segment is located in Pascagoula, Mississippi on 800 acres along the Pascagoula River. Amphibious Assault Ships We construct amphibious assault ships for the U.S. Navy, which include U.S. Navy large deck amphibious assault ships ("LHA") and amphibious transport dock ships ("LPD"). The LHA is a key component of the Department of the Navy's requirement for Expeditionary Strike Groups/Amphibious Readiness Groups, and design, construction, and modernization of LHAs are core to our Ingalls operations. In 2007, we were awarded the construction contract for USS America (LHA 6), the first in a class of enhanced amphibious assault ships designed from the keel up to be an aviation optimized Marine assault platform. We are currently constructing Bougainville (LHA 8) and Fallujah (LHA 9). In 2023, we were awarded a long-lead-time material contract for Helmand Province (LHA 10), and in 2024, we were awarded a contract modification for the detail design and construction of Helmand Province (LHA 10). The LPD program is a long-running production program of amphibious assault ships. We delivered USS Richard M. McCool Jr . (LPD 29) in 2024. We are currently constructing Harrisburg (LPD 30), Pittsburgh (LPD 31), and Philadelphia (LPD 32). In 2024, we were awarded a multi-ship procurement contract for the construction of Travis Manion (LPD 33), LPD 34 (unnamed), and LPD 35 (unnamed). Surface Combatants We are a design agent for, and one of only two companies that constructs, Arleigh Burke class guided missile destroyers ("DDG"), a class of surface combatant. We have delivered 36 Arleigh Burke class (DDG 51) destroyers to the U.S. Navy, including USS Ted Stevens (DDG 128) in 2025 and USS Jack H. Lucas (DDG 125) in 2023. In 2018, we were awarded a multi-year contract for construction of six Arleigh Burke class (DDG 51) destroyers and, in 2020, a contract to construct an additional Arleigh Burke class (DDG 51) destroyer. In 2023, we were awarded a multi-year contract for construction of six more Arleigh Burke class (DDG 51) destroyers, as well as the first option ship, for a total of seven ships. We are currently constructing Jeremiah Denton (DDG 129), George M. Neal (DDG 131), Sam Nunn (DDG 133), and Thad Cochran (DDG 135). 1 Table of Contents National Security Cutters The U.S.…
